Description
Technical field
The invention belongs to composite conducting fiber preparation field, particularly to the preparation method of a kind of cuprous sulfide/PET composite conducting fiber.
Background technology
In recent years, along with developing rapidly and universal of computer, telecommunications, microwave oven etc., electromagnetic radiation in human lives's working environment is day by day serious thus the normal operation of electronic equipment and the physiological health of the mankind are brought a lot of negative effect by that produce Electromagnetic Interference, for preventing static interference and Electromagnetic Interference, from mid-term in 20th century so far, for various uses, develop the material of various antistatic and electromagnetic shielding.Recent decades, the emphasis of research has turned to conductive fiber more, the antistatic effect of conductive fiber is significantly lasting, and not by the impact of ambient humidity, conductive layer reaches certain thickness or after conductive component reaches certain proportion, there is excellent electro-magnetic screen function, therefore conductive fiber development and application increasingly come into one's own.
The preparation method of conductive fiber has many kinds, and along with deepening continuously of research, according to the final performance of prepared fiber and preparation technology, people have been phased out some preparation methoies fallen behind.At present, the method being prepared into antistatic fibre mainly has three kinds: one to be with either physically or chemically making fiber surface form the coat of metal at textile surfaces such as fibers, this method often makes the feel of fiber become thick and stiff due to the coat of metal formed, it is difficult to textile process, and investment of production equipment is big, efficiency is low, and production cost is high；Two is chemically form semiconductor lamella at fiber surface, and chemical method technique is relatively simple, affects little on the physical and mechanical properties of fiber, and electric conductivity is better, but conduction durability is poor；Three is that electrically conductive particles is mixed in spinning melt; made the conductive fiber of skin-core structure or island structure by composite spinning, the Conductivity of Fiber electrical endurance prepared in this way is excellent, and less because adding conducting particles; do not damage the physical property of fiber, thus receive significant attention.But, when adopting this technique to prepare antistatic fibre, commonly used conducting particles size mostly is a μm level, does not have the characteristic of nano material, and in molding process, often increases the weight of the loss of equipment, is unfavorable for reducing production cost.Therefore, development cost conductive fiber low, function admirable is just particularly important.
Polyester fiber has the excellent specific properties such as higher-strength, high initial modulus, rub resistance, has a wide range of applications in a lot of field such as clothing, woollen blanket.But polyester fiber hydrophobicity is strong, it is easy to produce electrostatic, clothing can be caused mutually to be wound around, dust suction, impact dress, and electrostatic accumulation will discharge to a certain extent, can set off an explosion again in specific occasion and the electric discharge disaster such as fire.Therefore to overcome the strong electrostatic property of polyester fiber, it is necessary to polyester fiber is modified in some application aspect so that it is there is antistatic property.
Metal sulfide all has special performance in optics, Optical Electro-Chemistry, catalysis, environmental protection etc..They have good chemically and thermally stability, are a kind of good photoelectric materials.The characteristic utilizing metal sulfide is preferably at most fiber surface chemical reaction method to the method producing conductive fiber in application at present, this method is mainly through chemical treatment, namely by the dipping of reactant liquor, produce absorption at fiber surface, then pass through chemical reaction and make metal sulfide cover fiber surface.The method advantage is in that technique is simple, less costly, and the intensity of fiber, flexibility, slipping equivalent damage is less.In the eighties in 20th century, Japan is just developed into this kind of conductive fiber.Conductive compositions and electrical conduction mechanism have also been studied by specially, and the surface such as Japan's development covers the conductive acrylic fibre of the sulfide of copper, is first processed in copper ions solution by acrylon, then processes in reducing agent, the Cu on fiber2+Become Cu+With-CN complexation, the further conductive material of the sulfide of formation copper.Owing to these conductive materials define network on fibre structure, therefore electric conductivity is fine.Domestic patent 87104625.3,201510188325.1,200810084225.4 etc. all adopts production conductive fiber in this way.Owing to the cyano group on polyacrylonitrile fibre can produce complexation with copper ion, fiber is made to have electric conductivity.But terylene is due to interior molecules arrangement closely, intermolecular lacking hydrophilic-structure, therefore regain is only small, and moisture pick-up properties is poor, and antistatic behaviour is bad.Simultaneously as PET fiber surface lacks can produce the group of complexation with copper ion, so cannot directly adopt fiber surface chemical reaction method to prepare terylene conductive fiber.
Summary of the invention
